okf-tui is a full-screen terminal UI over OKF (Open Knowledge Format) bundles. It reads a bundle in the order the spec intends — index.md, log.md, then each directory — renders concept bodies as markdown, and finds within them. It browses and configures the per-user bundle registry, switches the active bundle, and searches every bundle in scope through one shared index, so the scores compare between them. It shows each bundle's standing (conformance and curation) wherever the bundle is named, and its knowledge graph as a set of facets to narrow by or follow into the file. It invents no analysis: the okf gem's pure core answers every question on screen.
